VANE-GOVERNOR FOR- STEAM-ENGINES, &C.

Specification of Letters Patent No. 17,623, dated June 23, 1857.

To all 'whom 'it may concern:

Be it known that I, FRANCIS GUsTINE, of Medford, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Regulators for Cut-Off Valves of Steam-Engines,of which the following is a full, clear, and eXact description,reference being had to the accompanying drawings, making part Oftllisspecification, in which- Figures l and 2 are front elevations; Fig. 3,an elevation at right angles to the above; Fig. 4, a plan.

In the said drawings A is a illar or stand through which passes a rod Bw ich is caused to turn in the pillar by any suitable connection fromthe engine applied to its lower end at a. To this rod near its top issecured the cross piece C which is carried around by the rotation of therod. From this cross piece rise the standards b in which turn the armsD. These arms are prevented from moving endwise by the enlarged portionc between two of the standards. To the outer end of each arm is attacheda metallic disk E which when the governor is at rest as in Fig. 1 hangsdown vertically. At the inner end of .each arm D is a toe e set at rightangles to the disk E, the

toe on one arm pointing in a direction opposite to that on the other.Over the upper end of the rod B is slipped a sleeve F. A pin f passesthrough the rod and slides in slots g in the sleeve, allowing the sleeveto rise and fall on the rod While it is carried around with it. By thevertical motion of this sleeve the closing of the valve is regulated.

The operation is as follows: As the speed of the engine increases thebar C and with it the disks E are revolved more rapidly and theresistance of the atmos here against the surface of the disks causes tem to be thrown back as in Figs 2, 3, and 4, turning the arms D andraising the toes e which lift the sleeve F. As the speed decreases thedisks fall toward the vertical position of Fig. 1 and the sleeve F islowered.

What I claim as my invention and desire to secure by Letters Patent is-The disks or vanes E operating directly upon the valve rod toes asdescribed, whereby the valve is actuated by the varying deflections ofthe vanes as set forth.

FRANCIS GUSTINE.
